They then pass over guide-plate o, and are seized between the forming-rolls c c, which are revolved by the crank. These rolls form a double bead on the curved strips and pass them onward between the horizontal rolls in m and die 17, which bend over the edges of the beads, form ing two nearly circular channels of unequal size. The rubber tube is fed through the guide 0, and inelosed in the larger of the two channels in the strips by the rolls t, n, and 02., which wrap the bead about the said elastic tube. The weather-strips now pass between the double-grooved clinching-rolls f f, which are revolved by the crank, and the rubber tube is by them firmly secured in the metallic bead, and the weather-strips are turned out in their completely-tinished form.
